The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel Nov 2014

The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel

Doctoral Dissertations

Nocturnal sleep has been shown to benefit memory in adults and children. During the preschool age range (~3-5 years), the distribution of sleep across the 24-hour period changes dramatically. Children transition from biphasic sleep patterns (a nap in addition to overnight sleep) to a monophasic sleep pattern (only overnight sleep). In addition, early childhood is a time of neuronal plasticity and pronounced acquisition of new information. This dissertation sought to examine the relationship between daytime napping and memory consolidation in preschool-aged children during this transitional time. Children were taught either a declarative or an emotional task in the morning, and …


Integrated Modeling Of Land Use And Climate Change Impacts On Multiscale Ecosystems Of Central African Watersheds, Simon Nampindo Nov 2014

Integrated Modeling Of Land Use And Climate Change Impacts On Multiscale Ecosystems Of Central African Watersheds, Simon Nampindo

Doctoral Dissertations

Assessment and management of ecosystem services demands diverse knowledge of the system components. Land use change occurring mainly through deforestation, expansion of agriculture and unregulated extraction of natural resources are the greatest challenges of the Congo basin and yet is central to supporting over 100 million people. This study undertook to implement an integrated modeling of multiscale ecosystems of central African watersheds and model the impact of anthropogenic factors on elephant population in Greater Virunga landscape. The study was conducted at varied scales, regional, landscape, and community. Regional study included watershed analysis and hydrological assessment using remotely sensed data implemented …


Attention Modulates Erp Indices Of The Precedence Effect, Benjamin H. Zobel Nov 2014

Attention Modulates Erp Indices Of The Precedence Effect, Benjamin H. Zobel

Masters Theses

When presented with two identical sounds from different locations separated by a short onset asynchrony, listeners report hearing a single source at the location of the lead sound, a phenomenon called the precedence effect (Wallach et al., 1949; Haas, 1951). When the onset asynchrony is above echo threshold, listeners report hearing the lead and lag sounds as separate sources with distinct locations. Event-related potential (ERP) studies have shown that perception of separate sound sources is accompanied by an object-related negativity (ORN) 100-250 ms after onset and a late posterior positivity (LP) 300-500 ms after onset (Sanders et al., 2008; Sanders …


Were Neandertal Humeri Adapted For Spear Thrusting Or Throwing? A Finite Element Study, Michael Anthony Berthaume Nov 2014

Were Neandertal Humeri Adapted For Spear Thrusting Or Throwing? A Finite Element Study, Michael Anthony Berthaume

Masters Theses

An ongoing debate concerning Neandertal ecology is whether or not they utilized long range weaponry. The anteroposteriorly expanded cross-section of Neandertal humeri have led some to argue they thrusted their weapons, while the rounder cross-section of Late Upper Paleolithic modern human humeri suggests they threw their weapons. We test the hypothesis that Neandertal humeri were built to resist strains engendered by thrusting rather than throwing using finite element models of one Neandertal, one Early Upper Paleolithic (EUP) human and three recent human humeri, representing a range of cross-sectional shapes and sizes. Electromyography and kinematic data and articulated skeletons were used …

Loss Of Cell Surface Agal During Catarrhine Evolution: Possible Implications For The Evolution Of Resistance To Viral Infections And For Oligocene Lineage Divergence, Idalia Aracely Rodriguez Apr 2014

Loss Of Cell Surface Agal During Catarrhine Evolution: Possible Implications For The Evolution Of Resistance To Viral Infections And For Oligocene Lineage Divergence, Idalia Aracely Rodriguez

Doctoral Dissertations

The divergence of the two superfamilies belonging to the Infraorder Catarrhini –Cercopithecoidea (Old World monkeys) and Hominoidea (apes, including humans) – is generally assumed to have occurred during the Oligocene, between 38 and 20 million years ago. Genetic studies indicate that this time period was one of active genetic evolution under strong purifying selection for catarrhine primates. This includes selective pressures on the glycoprotein galactosyltransferase 1 (GGTA1) gene and subsequent inactivation “clocked” at approximately 28 ma, possibly prior to the Cercopithecoidea/Hominoidea split. The GGTA1 gene codes for an a1,3 galactosyltransferase (GT) enzyme that synthesizes a terminal disaccharide, …


Youth Participation In Changing Food Systems: Toward Food Justice Youth Development, Krista Harper, Catherine Sands, Diego Angarita, Molly Totman Mar 2014

Youth Participation In Changing Food Systems: Toward Food Justice Youth Development, Krista Harper, Catherine Sands, Diego Angarita, Molly Totman

Krista M. Harper

We present results from a youth participatory action research (YPAR) project in which young people from Holyoke studied the school food system in order to make positive interventions in their school district. We used the Photovoice research method, placing cameras in the hands of youth so that they themselves could document and discuss their concerns and perspectives (Wang, et al., 1996). The research was designed to gain insight about the students’ knowledge of food, nutrition, and community food systems. The research also illuminated students’ impressions of public policy, active citizenship, and community building that have arisen out of food justice …


From Battery Cages To Barns: A Cost-Benefit Analysis Of A National Standard For Cage-Free Egg Production, Jonathan Ward Jan 2014

From Battery Cages To Barns: A Cost-Benefit Analysis Of A National Standard For Cage-Free Egg Production, Jonathan Ward

School of Public Policy Capstones

Legislation concerning the well being of farm animals has become a major focus in the animal rights movement, especially as it pertains to intensive confinement systems, such as housing egg-laying hens in battery cages. Informational asymmetries in the market for eggs represent a market failure, as producers have few incentives to inform consumers on modern egg production methods, which they may perceive as cruel. This study uses cost-benefit analysis to examine the effects of a hypothetical U.S. ban on caged egg production to assess whether such a standard would produce use and non-use benefits in excess of producer and consumer …
